Embodiment
VPLS implementation method provided by the invention, the groove position that the global configuration mode of VPLS business is improved to according to the professional place of VPLS is configured, and takes full advantage of the single-deck resource, reaches the maximized purpose of resource.Below in conjunction with accompanying drawing the present invention is made detailed explanation.
The VPLS implementation method comprises VPLS configuration and two steps of MAC address learning:
The VPLS configuration step is as follows:
(1) webmaster configures corresponding VPLS according to the professional related groove position of different VPLS, as shown in Figure 2, suppose that the VPLS1 business relates to groove position 1,2,3, the VPLS2 business relates to groove position 4,5,6, the VPLS3 business relates to groove position 7,8,9 ... so, according to groove position 1,2,3 configuration VPLS1, according to groove position 4,5,6 configuration VPLS2, according to groove position 7,8,9 configuration VPLS3.Because single professional single-deck is supported 12K VP, the VPLS example number supported of professional single-deck on the groove position 1,2,3 is 4K (supposing that each VPLS example comprises 3 VP) so, similarly, the VPLS example number supported of the professional single-deck on the groove position 4,5,6 and 7,8,9 also is 4K.And for VPLS global configuration situation shown in Figure 1, same VPLS configuration can be issued to all professional single-decks, do not belong to the single-deck that this VPLS business relates to and can receive this configuration yet, and scheme provided by the invention, it is professional that each single-deck is all set up identical VPLS, the heap(ed) capacity that whole set equipment VPLS can reach is single-deck capacity 4K, and the VPLS volume of business that whole set equipment is supported no longer is subjected to the restriction of single professional single-deck resource, reaches the purpose of professional single-deck resource maximum using.
Among Fig. 2, [4K+1,8K] expression can be set up 4K different VPLS, 4K+1,4K+2 ..., 8K represents ID number of VPLS, the VPLS of [the Isosorbide-5-Nitrae K] that sets up with groove position #1,2,3 makes a distinction.Because Fig. 2 is configured by the groove position to issue, the ID of the VPLS of each groove position can not repeat; But Fig. 1 is global configuration, and that each groove position is all set up is identical VPLS, and the ID of VPLS is the same.
(2) for each VPLS, set up respectively the mapping table between the local VP index of webmaster overall situation VP key assignments and described VPLS, in the described mapping table, the VP of same sequence number all has different VP call number and corresponding one by one with same webmaster overall situation VP key assignments on the professional single-deck of different slots position.
When the VPLS configuration that webmaster issues arrives each professional single-deck by corresponding groove position, can apply for the local VP resource of corresponding service single-deck, thereby set up webmaster overall situation VP key assignments to the mapping table between the local VP index, as shown in Figure 3, comprise groove position 1 for VPLS1(, 2,3, the professional single-deck a of difference plug-in mounting on it, b, c), local VP call number ID-a1 on the webmaster overall situation VP key assignments KEY1 corresponding groove position 1, local VP call number ID-c1 on local VP call number ID-b1 on the groove position 2 and the groove position 3, ID-a1, ID-b1 and ID-c1 be corresponding professional single-deck a respectively, b, VP1 on the c, according to this mapping table, the overall VP key assignments that the local VP call number of each professional single-deck is corresponding unique, overall VP key-value pair be the unique VP in certain VPLS example specifically.
The MAC address learning step is as follows:
As shown in Figure 4, webmaster is set up respectively VPLS1 and VPLS2, VPLS1 is corresponding professional single-deck a, b, the c that is inserted on the groove position 1,2,3 respectively, and VPLS2 is corresponding professional single-deck d, e, the f that is inserted on the groove position 4,5,6 respectively, and VPLS1 and VPLS2 carry out exchanges data by Cross Trade.
(1) the VPLS1 business is from the VP1 access of professional single-deck a, professional single-deck a on the groove position 1 finishes source MAC study, then utilize local VP index ID-A1 to search mapping table shown in Figure 3, obtain webmaster corresponding to local VP call number D-a1 overall situation VP key assignments KEY1, again the MAC of VPLS1, packet and overall VP key assignments KEY1 are encapsulated in and enter the Cross Trade broadcast tunnels in the MAC address learning message and broadcast.
(2) after the professional single-deck on other each groove positions receives above-mentioned MAC address learning message, search mapping table shown in Figure 3 according to the overall VP key assignments that carries in the MAC address learning message, obtain corresponding local VP call number.For example, after professional single-deck b on the groove position 2 receives the MAC address learning message, search mapping table shown in Figure 3, obtain the local VP call number ID-b1 of the professional single-deck b on the groove position 2, then use the MAC of VPLS1, packet and local VP call number ID-b1 to carry out abandoning this MAC address learning message after the MAC address learning.In like manner, the professional single-deck c on the groove position 3 determines that the VP of professional single-deck c is VP1.(professional single-deck d, e, f are inserted on the groove position 4,5,6 because professional single-deck d, e, f on the groove position 4,5,6 do not set up the VPLS1 example, set up the VPLS2 example), therefore failure when searching overall VP key assignments to the mapping table between the local VP index directly abandons this MAC address learning message.Like this, carry out MAC Address between the different single-deck and just avoided professional inundation after the study synchronously.
The present invention is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present invention, and every have identical or close technical scheme with the present invention, all falls within protection scope of the present invention.
